Name: Tsuga heterophylla / Menziesia ferruginea Forest
Reference: Western Ecology Working Group of...
Description: This regionally endemic plant association is described as a unit of potential natural vegetation from stands located in the Selkirk Mountains of Washington and Idaho, within the eastern-most portion of the Okanogan Highlands ecoregional section. The association occurs between 1370 and 1585 m (4500-5200 feet) elevation on cool, moist sites on gentle, south-facing slopes and ridgelines. It is the highest elevation <i>Tsuga heterophylla</i> association; frost and high snowpacks are common. Soils are silt loams to loams; in the Okanogans derived from volcanic ash over mixed colluvium or glacial till. The structure of stands of this evergreen, needle-leaved forest can vary greatly, depending on stand age. Mature stands will generally have an open appearance, with 75-95% canopy cover and large <i>Tsuga heterophylla</i> dominating. Younger, seral stands are codominated by dense canopies of <i>Abies lasiocarpa, Picea engelmannii</i> and <i>Tsuga heterophylla</i>. The understory is very species-poor, consisting of a deciduous shrub layer with cover over 50%. Characteristic shrubs include <i>Menziesia ferruginea, Rhododendron albiflorum</i> and <i>Vaccinium membranaceum</i>. Herbs are very sparse, with only <i>Goodyera oblongifolia</i> showing any constancy.
